On Sunday morning, thousands of runners across the world will set off in an unusual race. There is no determined distance – instead, competitors will be chased by a "catcher" car that will start after 30 minutes and gradually accelerate over time, eliminating runners one by one. When only one runner is left, the winner is found.

The UK race takes place at Silverstone. Colin Jackson will be running, as well international rugby player Max Evans and his brother Thom, who suffered a career-ending spinal injury at the age of 24. The race is being staged in aid of the Wings for Life spinal cord research foundation.

You can watch the race, plus interviews and more, on the live stream above from 9am on Sunday 4 May. The race itself starts at 11am.
